This invention relates to a mop having a divided head for washing,wiping or otherwise treating surfaces, such-as floors, walls, etc.

In mops of this nature the parts of the head are furnishedwith a readilyabsorptive, sponge-like facing, b means of which the water, etc, isapplie treatment and, after the facing of absorptive material has beensqueezed out, may again be removed.

It is the primary object of this invention to generally im rove. on mopsof this type so that the hea of the mop may be introduced belowrelatively low articles of furniture and into inaccessible corners, andso that the mop may be readily squeezed out without contaminating thehands.

This is accomplished by the fact that the handle of the mop is connectedto the head so as to be oscillator to the extent of approximately 180about t e same and to be capable of adwstment in any desired position.Further, there is provided on the movable handle a device connected withthe parts of the head, which device may be actuated in any position ofthe handle, and by means of which the parts of the head may be tightlypressed together and again moved apart. 7

@ther objects and advantages of the m- .vention will become apparent asthe description proceeds. a

lhe invention will now be described more fully with reference to theaccompanying drawings which illustrate the invention in two possibleforms of embodiment.

the position of the blocks according being a plan view of the head ofthe cording to Fig. 5 during the operation of squeezing out the water.

Fi 8 is a section taken on the line VIII- VII of Fig. 5.

. In the form of embodiment .according to Figs. 1-4 the head of the mopconsists of two block-like portions a and b, which are composed of woodor any other suitable material. The two blocks a and b are pivoted bymeans of pins 10' to a transverse holder comprising two metallic yokemembers 0. These yoke members are widened out in box-like fashion at f,and these box-like sections are firmly connected together at the apicesof the two yoke members. On the pins 1 there may be provided coilsprings p" having the opposite ends fixed to the blocks a, b and theyoke members a, by means of which the blocks a and b are moved into theposition according to Fig. 1, and which springs are tensioned in to Fig.2. To each block a and b there is detachably secured a sponge-like ad orother absorptive facing or fitting d, WhlCh may consist of rubber spongeor any other convenient material which W111 apply the water or othercleansing agent to the surface under treatment and again absorb thesuperfluous liquid when squeezed out. a i

At the point'where the two yoke members 0 are connected together thereis pivotally connected by means of a pin n a sleeve or socket h, whichserves for the attachment of the lower end of the handle 1'.

For the purpose of locking the handle 5 in thoseparticular inclinedpositions in relation to the head which are usually re uired hooks k areprovided on the yoke mem ers c engaging in eyes is on the socket in Toeach block portion a and b there is secured on the two end faces anactuating means, which may consist, for example, of a flexible wire m.The points of attachment m are so disposed that by the a plication of atensile force to the wires the b ocks a and b may be moved about theirins p in the manner indicated in Fig.2. all four end faces of the blocksa and b are passed through holes e into the box-like enhe wires. m from.

the pin n with which the socket h is pivotally secured to the okemembers/c or en- 'grip is pulled the wires m are subjected to a tensileforce, whereby the blocks a and b may be moved out of the position inFig. 1 into that according to Flg. 2. The wires m may also be conductedalong the outside of handle the handle, in which case the same are thenheld against the handle by means of clips,eyes or the like. It is notessential that the wires are conducted right up to the upper end of theand an opening might be provided laterally in the handle at a suitablepoint between its two ends, through which opening the wires are allowedto emerge for connection with the ,grip. If desired, small rollers maybe provided in or on the handle for guiding the wires.

' Preparatory to cleaning asurface thehead of the mop is immersed inwater in the position shown in Fig. 1, whereby the sponge-like .facingsor fittings absorb water in the usual manner. If the'mop is then passedbackwards and forwards with the facings of absorptive material engagingthe surface to be cleaned, the water is pressed out and the surfaceprovided-with a plentitude of water, sothat the dirt is loosened andpicked u by the facings d. The head of the mop wit the facings, maynaturally be immersed in the water as often as desired. For the purposeof again removin the water from the surface the parts a. and I arecompressed over a pail or other receptacle in the manner shown in Fig. 2b pullmg the handle 0, and accordingly t e wires m. By reason of thiscompression the water contained in the facings or fittings is squeezedoht so that only I very little remains therein, and the facingsorfittings are capable of absorbing water anew, the grip 0 thereupon beingreleased, whereby the locks a and 6 return under theaction of thesprings on the pins 3r) into the posi- I vtion shown in ig. 1. Therelatively dry mop is then applied to the surface under treatment, andthe facings d absorb the superfluous moisture. The mop is thereuponagain squeezed out in the manner described by I pulling the grip 0, themop being held for tings d. The facin of each block is composed of twoparts, etween which there is an intermediate spacet.

In this embodimentthe transverse holder for the head at the mop consistsof two straight plates 0', c, on which the two blocks are mounted inoscillatory fashion by means of the threaded bolts p'.' The threadedbolts p are all situated in the one horizontal plane. At the centrebetween the two ends of the plates 0' there is ivotall connected bymeans of pins'n, a for or U-s aped memher 0'', which possesss'es asocket or sleeve h. In this socket or sleeve there is secured the lowerend of the handle 11, which is capable of being moved together with thefork c" to.

the extent of 180- about the pins a. To each plate 0 there is pivoted asomewhat resilient arm is. having a plurality of holes. 'Ilhe arms k arebent in such fashion that the same are capable of engaging with one ofthe holes over a pin 9, which issecured laterally to the fork c. Bymeans of this arrangement the fork a", and accordingl the handle 2', maybe locked irf various inc i'ned positions in relation to the head of themop..

At the centre of each block a, b there is provided a recess, which isopen towards the opposite side of the blocks a and b, and serves in eachcase for the reception of a toothed segment or segment gear r or r. The

toothed segments are so arranged that their centre points coincide withthose ofthe pins 1) and that of each segment the part bearing the teethA rojects into the spaceft intermediate the" acings d. .The teeth ofthe'two segments r' and r for the blocks a and b are placed inengagement with .each other, so that when the one segment with'theappertaining head portion is caused to'rotate the second segment is alsomoved about its centre and moves the appertaining head portion. I

For secure attachment of the segments 1', r in the blocks a and b thereis mounted firmly on each an arm 8, which passes through a transversebbring'in the head, and is furnished on the outside of the block with a'the outside of the block, and by means of which the arm .9 of thesegment and the appertaining block are tightly connected.

To the one segment r t ere is secured an arm a, which projects with itsfree end into the space between the two head' portions (1 and b. To thefree end of the arm a there is pivoted by means of a pin 1) a rod w,which passes approximately vertically upwards in the space between thetwo parts a and b, and is pivotally connected by a pin a with a tierod 2This tie-rod y is conducted along thehandle 2", preferably through thesleeve h. The sleeve h, which firmly encompasses the handle 2', isbulged out for this particular purpose, as shown in Fig. 8, so that aguideway the rod 3 may be moved back-.

wards and forwards without obstruction.

If the rod is lifted or pulled by means of the 5 bent grip 2, it alsomoves the rod 20, and through the medium of the arm '0 thus rotates thesegment 7'' with its block b about the pins 32. The segment r moves thesegment r, and the two blocks a and I) thus being 10 brought into theposition shown in Fig. 7.

To prevent accidental displacement of the rod ft] the same may also beembedded outside of the sleeve h in an open roove in the handle 2", andat the upper on adjacent the grip 2; may possess a stud 2, which snapsinto a recess in the handle 71'. The rod 3 which is composed of iron,possesses a sufiicient natural resiliency to permit-of withdrawal of thestud z from the recess in the'handle z to permit actuation of the rod 3The manipulation of the mop accordi to Figs. 5-8 is similar to that asdescribe in connection with Figs. 1-4. By reason of the means y, w, o inconjunction with the toothed segments 1 ,9 the blocks a and b may becompressed in exactly thesame fashion as with the corresponding deviceshown in Figs. 1-4.

It will be understood that no restriction is made to the specificformsof embodiment shown in the drawings, which are shown merel by wayof example, and that various modi cations are quite ssible within the Imeanin of the above d cription and the annexe claims without departingfrom the spirit of the invention.
